I’m trying to flash the board with dual endstop version of the firmware but when I plug the usb in to my laptop its not listed under devices and drives. When I plugged the board in my laptop it said it was installing the drivers for the Rambo v1.4. Can I flash it with the sd card using the lcd display?
You can’t flash it from the sd card with this board.
The rambo should only need drivers in windows 7.
You also need to have 12V power, or it won’t be able to talk to the board. It is new, but I think it is so much easier, I think you should try using XLoader instead of platformio. The firmware.hex is at MarlinBuilder releases and you want the V1CNC_Rambo_Dual version.
